* | Delete the `Throw()` function from `absl::base_internal`.Gravatar Devin Jeanpierre2023-03-01
| | | | | | | | | | | | | | This was originally added in order to centralize the ifdefs, in cl/164484905. However, cl/337142938 undid this aspect of the change, because it broke on Android. What is left is vestigial: `Throw()` can be deleted at no loss, with a warning that should discourage us from ever reintroducing it.

* Update the predicate for `ABSL_INTERNAL_HAS_RTTI` for Windows builds.Gravatar Abseil Team2023-02-24
| | | | | | | | | | | | | | | | | | | Abseil defines `ABSL_INTERNAL_HAS_RTTI` by: ``` !defined(__GNUC__) || defined(__GXX_RTTI) ``` This predicate correctly decides rtti for GNU platforms. This predicate is always true for non-GNU platforms. It is not true that rtti is always enabled for non-GNU platforms. For example, when building with `cl.exe` and disabling rtti with `\GR-`, this clause is true. This leads to errors in Windows builds that disable rtti. This default behavior is not decidably correct, but the default behavior shouldn't change. It is better to guess that rtti is on, because if rtti is actually off, compilation will fail, and no programs will be harmed. This change updates the non-default behavior to include a check for rtti on Windows platforms. This change preserves the default behavior.

* Initialize ScopedMockLog.is_triggered_ with false.Gravatar Abseil Team2023-02-23
| | | | | | | | | In C++20, this happens by default, but in C++17, it's left uninitialized if no logs are sent and StartCapturingLogs is never called. The destructor then makes an attempt to access it, which is both unsafe and not very useful while it is uninitialized. Also add a test that expects the appropriate CHECK fail when StartCapturingLogs is not called. PiperOrigin-RevId: 511865440 Change-Id: Ie23ff3f901e926761d5f487e10d33c21c3bd43d3

Not sure if it can affect any real cases or not, though. Cast e_shentsize to loff_t instead of e_shoff. This makes both multiplication and addition to use loff_t type.

In other words, an observer measuring the time with a stop watch will now see the correct interval, even if the system clock is changed. Previously, the duration was added to the current time, and methods would wait until that time was reached on the possibly changed realtime system clock. The behavior of the synchronization methods that take an absl::Time is unchanged. These methods always wait until the absolute point in time is reached and respect changes to the system clock. In other words, an observer will always see the timeout occur when a wall clock reaches that time, even if the clock is manipulated externally. Note: ABSL_PREDICT_FALSE was removed from the error case in Futex as timeouts are handled by this case, and timeouts are part of normal operation.

A followup change will add an implemention of synchronization_internal::Waiter that can use std:mutex/std::condition_variable to implement the per-thread semaphore that absl::Mutex waits on. This implementation may at some point become the default on platforms such as Windows where there doesn't seem to be an easy way of supporting real absolute timeouts. In this case we can defer to their standard library to implement correct support. PiperOrigin-RevId: 510204786 Change-Id: Icf4d695013fd060abbd53dae23e71ea36f731565
